HOP-by-HOP Packet Forwarding Mechanism in Wireless Mesh Network
A wireless mesh network is infrastructure-less, "Self-organizing and self-configured" network where participating node automatically establishes and maintain connectivity amongst themselves. Such type of networks is difficult to provide internet access and connection in remote areas. In paper, lot of methods are proposed in order to handle problem in this network but in recent year the authors found expected transmission count metric and composite available bandwidth hop-by-hop routing mechanism. In this paper, they compare these two methods i.e. Expected Transmission count metric (ETX) and new path weight called Composite Available Bandwidth (CAB) method which captures the available path bandwidth information.
